Our Story
Founded in 2010, Steel Builders was established with a simple purpose: to make steel solutions smarter, faster, and more accessible for the Australian residential construction market. What began as a trusted supplier of structural steel has grown into a partner of choice for builders, engineers, and certifiers who value technical precision, customer-first service, and genuine, on-the-ground support.
In an industry where delays, rework, and complex compliance can slow progress, Steel Builders works alongside customers with engineered, compliant solutions focused on simplifying the build process and supporting more efficient, reliable outcomes on site.
In 2024, Steel Builders expanded its journey with the inclusion of Network Steel. Based in Queensland, Network Steel brought established manufacturing capability, deep local knowledge, and a shared commitment to quality and compliance. Together, we employ more than 200 families and remain proudly Australian owned, focused on supporting the residential construction industry with dependable, compliant steel solutions.
Steel Builders and Network Steel
are building smarter, together.
